[detailed description of the invention]
The invention will be further described below in conjunction with the accompanying drawings:
As shown in Figures 1 to 7, a kind of demolding structure, including front template 1 and can be with its folding
Rear pattern plate 2, be provided with in described rear pattern plate 1 can relative its oblique slanted kicking block 3 slided,
The end of described slanted kicking block 3 is provided with the groove 4 of the position of bone 101 shaping for product, described
The side of slanted kicking block 3 be provided with lateral through hole 5, be provided with and oblique top in described lateral through hole 5
Block 3 coordinate and for product 100 button bit 102 be molded slide block 6, described button bit 102
With on being mutually inclined of being located on product 100 of the position of bone 101 or vertical inwall, described slide block
Connect on 6 and have when die sinking the actuator 7 driving slide block 6 to exit in lateral through hole 5, institute
Rear pattern plate 2 side stated is provided with the ejector retainner plate 8 of setting with interval, described ejector retainner plate 8 with
Be provided through between product 100 rear pattern plate 2 and slide block 6 after lateral through hole 5 exits for
By the thimble 9 of product 100 jack-up, be provided with between described slanted kicking block 3 and ejector retainner plate 8 with tiltedly
What jacking block 3 connected is used for promoting the oblique slip of slanted kicking block 3 to make the push rod of product 100 demoulding
10, position corresponding with push rod 10 end on described ejector retainner plate 8 is provided with deep gouge 11.?
In traditional demolding structure, if running into being mutually inclined or designing on vertical inwall at product
When the position of bone 101 protruded and button bit 102, traditional demolding structure can not the demoulding, now product
Designer has to redesign product, changes product structure, causes product structure complicated, increases
Add cost, and the demolding structure of the present invention just solves this problem so that be mutually inclined
Or the product 100 of the position of bone 101 and button bit 102 devising protrusion on vertical inwall still can
Enough smooth demouldings, reduce product cost, and demolding structure are simple.
As shown in Figures 5 to 9, described actuator 7 includes driving block 71, described
Driving block 71 to be provided with the oblique slot 72 of inclination, described slide block 6 is provided with can be oblique
The slide guide bar 12 slided in groove 72, described driving block 71 is additionally provided with and is subject to when die sinking
The pull bar 73 that the rear die holder 13 of motion drives and drives drive block body 71 to move.
It is set in push rod as it is shown in figure 5, be provided with between described slanted kicking block 3 and ejector retainner plate 8
Spring 15 on 10.
As shown in Figures 6 to 9, described slide block 6 top is laterally provided with the boss 16 of protrusion,
Boss 16 described in when matched moulds stretches in described lateral through hole 5.
As it is shown in figure 9, described slanted kicking block 3 is two, described slide block 6 is two and sets
Between two slanted kicking blocks 3, described actuator 7 is located between two slide blocks 6.
As shown in Figure 8, Figure 9, described oblique slot 72 is four, and is respectively provided at two-by-two
Driving the both sides of block 71, described slide block 6 is provided with bayonet socket 14, described slide guide bar 12
Being located on bayonet socket 14 inwall, described driving block 71 through bayonet socket 14 and keeps slide guide bar
12 are placed in oblique slot 72.
As shown in Fig. 5, Figure 10, described pull bar 73 includes being connected also with driving block 71
Through the straight bar section 731 of rear die holder 13, the end of described straight bar section 731 is provided with and externally protrudes out in
Straight bar section 731 is placed in the protuberance 732 in the counterbore 17 of rear die holder 13.
Can be for thimble 9 as it is shown in figure 5, be additionally provided with between described rear pattern plate 2 and ejector retainner plate 8
The gripper shoe 18 passed with push rod 10, described spring 15 withstands on gripper shoe 18 and slanted kicking block
On 3.
Operation principle:
It is assembled to demolding structure of the present invention in mould carry out producing (as shown in Figure 10), when needing
When wanting product 100 demoulding, front die holder 19 and rear die holder 13 are opened, front template 1 and rear pattern plate
2 open, owing to the protuberance 732 on pull bar 73 is positioned at the counterbore 17 of rear die holder 13,
When rear die holder 13 is opened, rear die holder 13 drives pull bar 73 to move, and therefore pull bar 73 traction is driven
Motion block body 71 moves, and the slide guide bar 12 on slide block 6 is positioned at drive on block 71 oblique
In groove 72, so when driving block 71 to move along a straight line, driving block 71 then band movable slider
In 6 boss 16 on medial motion, the slide block 6 then lateral through hole 5 from slanted kicking block 3
Exit, at this moment exist for gap between button bit 102 and the inwall of lateral through hole 5 of product 100,
Then ejector retainner plate 8 travels forward, and ejector retainner plate 8 promotes thimble 9 to travel forward, due to boss
16 exit, so product 100 can be by thimble 9 jack-up forward, and due to ejector retainner plate 8
The upper position corresponding with push rod 10 is provided with deep gouge 11, so when thimble 9 is to sinciput product 100
Time, the end of push rod 10 fairly falls in deep gouge 11, say, that now push rod 10 will not
Travelling forward, slanted kicking block 3 now remains stationary as, and this is also it is prevented that the position of bone 101 is also located at recessed
If the situation that time in groove 4, slanted kicking block 3 oblique movement forward can make the position of bone 101 damage occurs.
When the position of bone 101 of product 100 is ejected in groove 4 completely, ejector retainner plate 8 promotes push rod
10 travel forward, and then promote slanted kicking block 3 oblique movement forward, slanted kicking block the most oblique
Motion is made up of, the most tiltedly linear motion forward and two componental movements of linear motion to inner side
Product 100 is just ejected and the demoulding by jacking block 3 completely, and ensures the excellent of product 100.
